यदि (P(A)) में (16) अवयव हैं तो (A) में कितने अवयव होंगे?
If (P(A)) has (16) elements, how many elements does (A) have?
Explanation opens after your attempt
C. (4)
Concept
If (A) has (n) elements, then (P(A)) has \(2^n\) elements. From \(2^n=16\), (n=4).
Why this answer is correct
The correct answer is C. (4). If (A) has (n) elements, then (P(A)) has \(2^n\) elements. From \(2^n=16\), (n=4).
Exam Tip
यदि (A) में (n) अवयव हों तो (P(A)) में \(2^n\) अवयव होते हैं। \(2^n=16\) से (n=4) है।
